dc.description | Several by-products resulting from processing agricultural products were used successfully
as feeds for livestock. Potato pulp, the residue remaining
after water extraction of starch from the raw potato, had such potential. A potato starch extraction plant at Grafton, North Dakota which produced about 2,500 tons of dry potato pulp
a year. Drying this pulp results in a “ gritty powder” material which can be stored in conventional storage, transported and mixed with other feeds. Dried potato pulp is lower in protein, higher in fiber (acid-detergent method) and higher in ash (minerals) than usual for the common feed grains. As it appeared that this potato by-product varied somewhat due to area of potato production and the
method of extracting the starch. Because of these variations, it was deemed necessary to evaluate the potato pulp in rations used in North Dakota. Two experiments are reviewed on this topic. Both experiments indicated that potato pulp can be used effectively up to levels of 25 % of the rations for fattening of cattle. | |
